The First Underground Railway
The first underground railway ever built was London’s Metropolitan line, built in 1863. Londoners call their underground “the tube”. There are 273 different stations now and the deepest station is Hampstead, 58 meters below the ground. It is also worth mentioning that the London underground is the longest in the world.
Thus, if all the tube lines were placed end to end, one end of the line would be in London and the other in Land’s End, the westernmost point in Britain. Although it may not seem easy to believe, visitors don’t find it difficult to travel by tube in London as all the lines have different signs and different colors.
